Hi, I bought a Powerbook Titanium 667Mhz about 3 months ago. It's the gigabyte eithernet model with 512mb of ram and a 30GB HD. I noticed it's very slow when switching between multiple apps like Photoshop, Freehand and Flash(I'm a web designer). Even the IE is very slow(I know IE mac version sucks). So I got a copy of Navigator, but it doesn't appear to be running any faster than the IE. I use Jaguar by the way. A friend of mine told me to partition my HD so it would make the machine run faster. So now I have 4 disks, 3GB for the Jaguar, 1GB for OS9, 10GB for apps and the rest goes to my work stuff. The performance is still not up to my Pentium 3 733 dual processor PC! People been telling me to get more ram(1 GB or a faster machine(1GHZ model). I only had this thing for about 3 months and I spent $2500 on it. Frankly, I haven't put this thing to much of use as I had hoped for, and people are talking about upgrading already. I'm not justified. I decided to go with a Mac when I was choosing between a Toshiba laptop and a PB. I've heard a lot of great things about PB and OSX. The "Switch" thing, you know. However, I'm disappointed with this PB so far.
